Well Integrity

Integrity by Design

Integrity starts with well construction, and Expro builds it in from day one.

• Drilling optimisation tools maintain borehole stability
• Tubular handling systems prevent damage to casing and tubing
• Torque-turn systems ensure connection integrity during make-up
• Cementing technologies enhance placement and bond quality
• Wellbore clean-out equipment prepares packer seal zones

At this stage, we don’t just construct wells, we create integrity that lasts.

Evaluating Integrity

Even the best-built wells face challenges over time. Expro’s sensor-led diagnostics approach rapidly identifies and quantifies well conditions and issues that threaten integrity.

Using our extensive suite of surveillance tools including Distributed Fibre Optic Sensing (DFOS), Ultrasonics, Cement Bond logging, and Calliper logging, all deployable via operationally efficient multi-mode conveyance systems, we assess tubular and cement condition, detect leaks, and interpret dynamic well behaviour.

Supported by our Global Data Analysis Centre, we rapidly turn uncertainty into clarity, transforming data into insight and action.

Remediating Integrity

When integrity is compromised, Expro moves fast to restore it.

• Core expandable patches repair connection or tubular leaks and isolate corrosion
• Octopoda® remediates annulus integrity issues at the source
• CoilHose® reinstates DHSV integrity via high-pressure chemical jetting

Every intervention is engineered to be operationally efficient, cost-effective, and minimally intrusive, reinstating well integrity and restoring production uptime.

Assuring Integrity 

Assured well integrity demands vigilance.

SafeWells®, Expro’s Well Integrity Data Management system, delivers continuous surveillance and risk tracking, enabling early issue detection and proactive remediation before costly shut-ins occur.  Aligned with international well integrity standards and regulatory expectations, SafeWells® strengthens safety cases and ensures full auditability.

By combining digital assurance with field intervention capability, Expro offers a complete integrity assurance ecosystem from data to delivery.

Decommissioning Integrity

When a well reaches end of life, assurance becomes everything.

Expro’s Well Decommissioning solutions span Reservoir Isolation, Completion Recovery, Cement Retainers, Barrier Placement, Annulus Remediation, and Environmental Plug Setting, ensuring wells are safely and permanently decommissioned.

With a proven record of reliability, zero harm, and full regulatory compliance, we provide confidence that integrity endures in decommissioned wells for the rest of time.

From well construction to decommissioning and beyond, Expro safeguards well integrity and your reputation at every stage of the well lifecycle.
